             Summary: IDL code-generation generates too-long literals for very large schemas
                 Key: AVRO-1316
                 URL: https://issues.apache.org/jira/browse/AVRO-1316
             Project: Avro
          Issue Type: Bug
          Components: java
            Reporter: Jeremy Kahn
            Priority: Minor


When I work from a very large IDL schema, the Java code generated includes a schema JSON literal that exceeds the length of the maximum allowed literal string ([65535 characters|http://stackoverflow.com/questions/8323082/size-of-initialisation-string-in-java]).  

This creates weird Maven errors like: {{[ERROR] ...FooProtocol.java:[13,89] constant string too long}}.


It might seem a little crazy, but a 64-kilobyte JSON protocol isn't outrageous at all for some of the more involved data structures, especially if we're including documentation strings etc.

I believe the fix should be a bit more sensitivity to the length of the JSON literal (and a willingness to split it into more than one literal, joined by {{+}}), but I haven't figured out where that change needs to go. Has anyone else encountered this problem?
